17 Claims.

This invention relates to separable fasteners employing tapes or stringers having coupling links arranged and'spaced longitudinally of one edge thereof and more particularly to the slider 5 employed for coupling and uncoupling the stringers; and the object of the invention is to into the several positions permitting free movement of the slider on the stringers and also toy retain the slider against movement thereon; a further object being to provide a retaining member of the class described having a V-shaped portion disposed within the channel of the slider to serve as means for guiding the links of the stringers and to facilitate separation thereof when said member is in what may be termed a neutral or inoperative position, said pin member being disposed at the forward end of the transverse partition wall of the slider and forming in conjunction therewith the contractedside walls extending in the direction of the contracted or object being to provide said pin member of the portion thereof disposed outwardly of one side wall of the slider with a nger piece or pull part which may be fixed or movably supported in connection therewith; a still further object being to provide means for frictionally retaining the pin part in its neutral or inoperative position; and with these and other objects in view, the invention consists in a device of the class and for the purpose specified which is simple in construction, eilicient in use, and which is constructed as hereinafter described and claimed.

The invention is fully disclosed in the follow' ing specification, of which the accompanying drawing forms a part, in which the separate parts of my improvement are designated by suitable reference characters in each of the views, and in which:

Fig. 1 is a plan view of one form of slider which I employ illustrating the same applied to a part of two stringers of a separable fastener.

Figs. 6, 7, 8 and 9 are plan views of modified forms of sliders which I employ showing the same detached.

Fig. l is a section on the line Ill- I0 of Fig. 9; and, y

` Figs. 11, 12 and 13 are plan views of other forms of sliders which I employ.

For the purpose of illustrating one use of my invention, in Figs. 1, 3 and 4 of the drawing I have shown a portion of two separable rfastener stringers I0 and II, onrone longitudinal edge portion of each of which are secured links I2 and I3 adapted `to be coupled and uncoupled as in other devices of this class. At I4, I have shown a slider employed for coupling and un- 20 coupling the links of the stringers, the slider consisting of top and bottom walls I and I6 joined together centrally of the wide end portion thereof by a body I1 to form two channels I8 and I9 for the links I2 and I3 at the wide end portion of the slider, which channels converge into a single channel 20 at the narrowor contracted end of the slider. The top and bottom walls or plates I5 and I6 of the slider include inwardly extending side flanges I5a, Ilia which engage the links of the fasteners to aid in coupling the same together.

At 2 I, I have shown a retaining member, wedge or cam in the form of a pin transversing the slider, preferably adjacent the wide end portion thereof and also preferably arranged forwardly of the coupling body I1. The pin includes an enlarged head or finger part 22 disposed outwardly of one wall or plate of the slider preferably the top wall I5. The other end of the 40 pin is riveted over as seen at 23 to retain the same against displacement from the slider while permitting free rotation of the member 2| in the slider.

Opposed side walls of the pin or member "I-l 4.5'

are cut away or beveled as seen at 24 where the v pin registers withthe channels I8 and I9 as well as the channel of the slider so as to form contracted walls on the front of the" coupling body I'I as clearly seen in Fig. 3 of ythe 50 drawing to permit free passage of the links I2 stringers I 0 and II. However, in rotating the part 22 to the right or to the left, or in fact, 55

into a position at 180 to that shown in Fig. 1 of the drawing, the unrecessed portion of the pin or member 2| will be moved into engagement with the links of the fastener to forcethem in'to engagement with the side flanges or walls |5a, |60, of the slider to securely retain the slider against movement on the stringers or to act as a cam or wedge between the links of the stringers to prevent movement of the slider thereon. One of the several locked or retained positions of the pin or member 2| is illustrated in Fig. 4 of the drawing.

The enlarged part 22 as shown in Figs. 1 to 5 inclusive includes an extending arm portion 25 having a bead 26 at 'the inner surface thereof to engage a socket or recess 21 in the top wall I5 of the slider to frictionally retain the member 2| in its neutral or inoperative position as seen in Figs. 2 and 3 of the drawing. With this construction, a finger piece or pull 28 is also employed, the same being pivotally supported in connection with the part 22 as indicated at 29. The nger piece or pull is also provided with an aperture 3|) adjacent the free end thereof tofacilitate attachment of a strip or ribbon thereto if desired in the manner illustrated in Fig. 8 of the drawing.

In Figs. 6 to 13 inclusive, I have shown several modified forms of construction, but in all of said figures the slider is substantially of the same structure as the slider shown in Figs. 1 to 5 inclusive as is also the internal structure of the pin or member 2|. For this reason, said parts will be identified by the reference numerals as follows. In Fig. 6, |4a represents the slider and 2|a the pin member; in Fig. '7, these parts are represented at |411, 2lb; in Fig. 8, at |4c, 2|c; in Figs. 9 and 10, at |4d, 2|d; in Fig. 11, at |4e, 2|e; in Fig. 12, at |.4f, 2li; and in Fig. 13, at |4g and 2|g.

In Fig. 6 of the drawing, the enlarged portion 22a, of the member 2|a is in the form of a rectangular block to which is pivotally coupled a finger piece or pull 28a in the form of a horse shoe by means of which the slider may be moved longitudinally of the stringers and also by means of which the member 2|a may be rotated into several positions to retain the slider against movement on the stringers.

In Fig. 7 of the drawing, I have shown at 22h an enlarged part on the member 2lb which has an apertured extension 3| normally extending in the direction of and preferably beyond the wide end portion of the slider and with which a pull tape or other member indicated in dot and dash lines at 32 may be coupled.

In Fig. 8 of the drawing, I have shown at 22e an enlarged portion on the member 2|c which has apertured extensions 3|a and 3 Ib similar to the extension 3| but extending in opposite directions from the pin member 2|c. This construction may be used to support a pull tape or ribbon 32a or also as a means for locking and retaining the slider in the manner taught in Figs. 9 and 10, utilizing the apertured end 3|b of the part 22e forthis purpose.

In Figs. 9 and 10 ofthe drawing, I have shown a part 22d substantially similar to the part 22h, but in this construction, the slider also includes a projecting apertured portion 33 adapted to register with the apertured end portion 3|c of the part 2|d to receive a padlock or the like 34 for locking the slider against movement on the stringers. With this construction, when the part 22d is in its locked position as seen in Figs. 9 and 1|), the pin'member 2|d is in locked p0- simon instead ortho position which is illustrated in Fig. 7 oif the drawing. In this connection it will be understood that with all of the constructions shown, the position of the enlarged part or finger portion 22-22g may assume any angular position on the slider when the retaining or wedge pin member is in locked or operative position depending entirely upon the fancy or desire of the manufacturer in the different uses of the fastener. In other words, some manufacturers might require that the part 22-22g assume positions such as shown in Figs. 1, 6, 7, 11, 12 and 13 when the pin member is in its operative position and an angular position to those named when said pin member is in inoperative position as would be the case with the structure shown in Figs. 9 and 10.

In Fig. 11 of the drawing, the part 22e is in the form of a semi-pear-shaped member having a wide end portion 35 normally arranged at the wide end portion .of the slider and a contracted end portion 36 normally karranged adjacent the contracted end of the slider. This part will be relatively at and will adapt the slider to separable fasteners for use on gloves and other apparel of this type or where the need for a pull or finger piece part is not necessary.`

In Fig. l2 of the drawing, the part 22f has a contracted end portion 31 normally extending in the direction of the wide end portion of the slider and terminating in .an enlarged knob or f head 38 which may be aperturedl as indicatedl at 39 to receive a pull chain or' cord if desired.

In Fig. 13, the part 22g is substantially simiiar to the part 22e of Fig. 11 except' that the contracted end 40 includes an upwardly projecting apertured knob or head 4| which will serve as a finger piece and with which a pull chain or cord may be attached.

With all of the forms of construction shown, the pin member in addition to serving as means for securing or retaining the slider against movement on the stringers also serves to couple the side walls I5 and I6 of the slider together. When the slider is.made of a single die cast body as shown in the accompanying drawing, this pin member will serve to reinforce the slider. However, in this connection it will be understood that myy invention is applicable to sliders of any desired form and construction, and the particular form and contour of theV retaining or wedging member employed may be modified to suit the slider as well as the particular links employed on the stringers.
